1.

A.Embryology

B. Evolution Genetics

C.Comparative Anatomy

2.

A. All the bacteria becoming resistant to the specific Antibiotics

B. The Bacteria becoming nonresistant to specific Antibiotics

C. Less Bacteria becoming resistant to the specific Antibiotics

1. B. Evolution Genetics

2.C. Less Bacteria becoming resistant to the specific Antibiotics

Explanation:

Evolution genetics is the field in which evolutionary changes in genome are studied. Here, the bacterial population was exposed to the antibiotic. In response, some bacteria showed mutations in their genome which made them resistant to the antibiotic. Since the genetic composition of bacteria has changed and made them to evolve, it would be a part of evolution genetics.

The fewer bacteria which showed these mutations became resistant to that particular antibiotic. However, this does not mean that the entire population will become resistant to the antibiotic. It is going to take a long time.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
